PRESS FOR WHEAT-BRAN, 85C.

SPECIFICATION forming part of Letters Patent No. 293,603, dated. February 12, 1884. Application filed November 28; 1883. (No model.)

To aZZ whom, it may concern:

Be it known that I, MELcHEsEDEcK Y.

I Tnorrrsoma citizen of the United States,residing at Arkadelphia, in the county of Clark and State of Arkansas, have invented certain new and useful Improvements in Presses for vertical longitudinal sectional view. Fig. 3

- is an end view. Fig. 4 is a sectional end view.

Figs. 5, 6, 7 and 8 are detail views.

This invention has relation to presses for wheat-bran, cotton, or hay; and it consists in the construction and novel arrangement of devices, as hereinafter set forth, and particularly pointed out in the appended claims.

The object of this invention is to utilize the effective force of two screws having their threads reversed with respect to each other, so that pressure will be applied to the mass in the baling-box in opposite directions, and to utilize the mass and leverage of the balingbox in working the screws.

In the accompanying drawings, the letter A designates the frame of the press, which should be solidly constructed,having the end uprights or pillars, B, which are bound together by means of longitudinal ties and sills, as at G O, towithstand pressure outward upon the pillars. The baling-box D is of horizontally-elongated rectangular form, having four substantial horizontal timbers, a a, forming the corners of the framing, and supporting'the side boards, I) b. An opening is left at c, in the middle portion of the box, for the escape of the pressed article. At each end of the box three sides, b, are permanently secured to the framing-bars a. The

dles 6, whereby they may be adjusted or taken away from the box. These doors'd are se- Fig. 2 is a -'which encircle the box and bind the timbers thereof firmly together. The inner ends of the box-boards b b and of the movable doors (I d are beveled on their inner sides, as indicated at g, to receive the outer edges, h, of the headless press-box F, which is designed to fit in the middle portion of the baling-box, be tween the end portions G G, which are provided with permanentside boards, as hereinbefore described. When the middle headless box or rectangular tubular section, F, is put in position between the end portions G G ofthe balingbox, a continuous baling-chamber is. formed between the ends or heads H H of the baling-box. WVithin this chamber, on each side,

' box, and are provided with the screw-stems L L, which have their threads reversed with reference to each other, said screw-stems pass ing through central openings, 7c,- in the ends or heads H of the baling-box, and through fixed nuts l in the pillars B of the frame.

In the chamber of the baling-box, between the followers and the headless box or packingbox F, are placed the loose heads m, adapted,

' when the followers move toward the. box F, to

be carried thereto, as the material in the baling-box is compressed, until, the pressure being complete, the heads at enter the ends of the baling-box. These heads are then to be nailed in position to the box F, and then, the movement of the screws being reversed, the wedges and doors are removed, and the packing-box, with its contents, is allowed to drop out of the baling-box. Another headless box can then be introduced into position for a fresh charge. The screws are reversed by the rotation. of the baling-box, which turns the followers to which they are secured.

M M indicate the circular cast ends of the is packed with remarkable density.

zontal timbers of the baling-box, the bolts be- 1 ing secured by countersunk nuts near the ends of said timbers. The bands or straps which encircle the baling-box are made with reversely-threaded ends (1, said ends being connected by a rotary coupling or double nut, which can be turned to tighten the bands when necessary. The screw-stems L of the followers extend through the openings k of the ends of the baling-box, and form journals on which the box turns. The end castings, M, of the box are formed with collar projections 1- around the openings 7:, which serve to bear against the inner walls of the large nuts, while the journal portions 25 of said nuts pass through said openings in the cast ends. In the rims of the wooden circles P are secured radially-projecting handles 8, whereby the box can be turned manually when power is not used. The followblocks are of ordinary construction, each having a collar-plate, 'n, bolted to its back, and formed with a central bearing for the end of the screw-stem, which is designed to be received'into the follow-block, and to be secured thereto by means of a transverse pin, w, passing through a slot, m, in the follower and a slot in the end of the screw-stem.

R indicates a locking-pin or movable stop having a bearing in the frame, and adapted to be placed in position to engage a portion of the baling-box, to hold it steady and keep it from turning when it is being filled. The large bearing-nuts Z are set into the pillars of the frame, and-are secured thereto by means of transverse bolts .6, which engage transverse bearings 10, made in the upper and lower portions of said nuts.

\Vhile this press may be used for any substance, it is especially adapted to compress wheat-bran into small compass for shipment. The force required is not great, and the bran The side boards of the press are usually perforated with small holes], to allow the air to pass outward, as well as to afford conductive means to the electricity developed as the bran or other substance is being compressed by the movement of the followers toward each other.

Having described this invention, what I claim, and desire to secure by Letters Patent,

8. The combination, with a rotary balingbox having cast and peripheral]y-toothcd circular ends, of the large fixed bearing-nuts, the followers having reversely-threaded screwstems, and the driving cog-wheels engaging the teeth of the cast ends, substantially as specified.

l. The rotary press-box having the followers in opposite ends and their reversely-threaded screw-stems, the end castings and the wooden circles having radial handles, and the binding-straps encircling the timbers of said pressbox, substantially as specified.

5. The combination, with a rotary pressbox having end chambers and a-middle opening, of a headless packing-box in the middle opening, oppositely-moving followers in the end chambers having reversely threaded screw-stems, and loose heads of the packingbox moving in the end chambers with the followers to the packing-box, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses. M. Y. THOMPSON. Witnesses:
